Complete 10-Bit 30 MSPS

CCD Signal Processor

AD9846A

PRODUCT DESCRIPTION

FEATURES

The AD9846A is a complete analog signal processor for CCD

applications. It features a 30 MHz single-channel architecture

designed to sample and condition the outputs of interlaced and

progressive scan area CCD arrays. The AD9846A’s signal chain

consists of an input clamp, correlated double sampler (CDS),

Pixel Gain Ampliﬁer (PxGA), digitally controlled variable gain

ampliﬁer (VGA), black level clamp, and a 10-bit A/D con-

verter. Additional input modes are provided for processing

analog video signals.

2 dB to 36 dB 10-Bit Variable Gain Ampliﬁer (VGA)

Low Noise Clamp Circuits

Analog Preblanking Function

10-Bit 30 MSPS A/D Converter

Auxiliary Inputs with VGA and Input Clamp

3-Wire Serial Digital Interface

3 V Single Supply Operation

Low Power: 100 mW @ 2.7 V

48-Lead LQFP Package

The internal registers are programmed through a 3-wire

serial digital interface. Programmable features include gain

adjustment, black level adjustment, input conﬁguration, and

power-down modes.

APPLICATIONS

Digital Still Cameras

Digital Video Camcorders

Industrial Imaging

The AD9846A operates from a single 3 V power supply, typi-

cally dissipates 117 mW, and is packaged in a 48-lead LQFP.
